The Tucson-based mining company Asarco has agreed to pay union workers about $10 million in disputed copper price bonuses.

Workers have been on strike after walking off the job in mid-October.

Asarco had been fighting the past several years against paying the bonuses but ultimately lost the battle last month.

The Arizona Daily Star reported that Asarco was forced to pay after the U.S. Supreme Court declined to review a lower court ruling upholding payment of the bonuses.

According to the United Steelworkers, Asarco’s lawyers sent an email to their lawyers promising payment. The payments will include interest and cover bonuses from the third quarter of 2011 to the first quarter of 2015.

The union says Asarco has promised to begin making the payments Nov. 6. To check out the full release, you can find it on the United Steelworkers website.
